Shift either too hard or wont shift at all. I have to stop turn it off and restart. Sometimes that works.
rpm ramp up when shifting... dragging.... hard shifts. Engine code was 1st 2nd gear shift solenoid
Transmission control solenoid failed. At this point the entire transmission was rebuilt.
Shifts really hard when trying to get up to speed on an on ramp or taking off frm a stop light. I find that if possible let her sit rest for a bit and she's good to go for a while. After a long day of stop and go and hills she was struggling to shift and when she finally did she over heated. By the time I was able to pull over I had a cracked head. Her shifting and over heating was immediate, not sure if the shifting problem caused the over heating but it seemed that way.
Shifts smooth for awhile.then starts to shift hard and seems to run rough.some times when I start it the trc control light comes on
My rpm is very high it jerks some time and after 35mph it runs very rough it also has the trac light on and service traction
Transmission has been acting up for years. Overheats, shuts down completely. Rough shifts, rolls backwards in Drive, engine races but does not go into gear when accelerating from a stop sign, engine races between 1st and 2nd gears. Had the pressure control solenoid replaced several years ago, but the improvement was only temporary. Also, the AC is not working.
